说明：  这就是陈建春的《用Visual C++开发GIS系统》的配套代码。 用来给初学者熟悉VC++图形编程很不错，我当初学MFC的时候就是照着这本书上手的。但作为一个GIS系统来说缺少一些必要的 要素，比如大数据量的管理、空间索引、符号化、投影等等等等等。以现在的眼光看来整个系统的架构设计也不是太好。 这本书再版后改名为《矢量图形系统开发与编程》，内容变化不大("using Visual C development of GIS systems" supporting code. For beginners to the VC familiar with graphical programming quite well, and I had the time to learn MFC is shining on this book in the business. But as a GIS systems lack the necessary elements, such as the large amount of data management, spatial indexing, symbols, such as projectors, etc.. Now the point of view of the entire system architecture design is not too good. This book reprinted later renamed as "vector graphics systems development and programming", little change)

使用VC生成COM组件的方法，里面对VC生成不同形式的COM接口参数的方法，对COM组件不熟悉的朋友会是一个很好的学习资料！(COM components using VC generation method which generates on the VC parameters of different types of COM interfaces methods, and COM components are not familiar with the friend would be a good learning materials!)

这是VC的一个addin的源代码，将其复制到vc下面的addin目录，然后加载后，可以用它来查看调试中的CDC。(This is an addin VC's source code, copies of the following vc addin directory, loaded, can be used to check the CDC debugging.)
